Competitors to Microsoft Office receive plenty of attention in the blogosphere these days. Whether it’s Google announcing a new mobile or social feature in Docs, Zoho a new API partner, or the recent buzz around the future of Open Office without Oracle -- it’s natural to wonder how much traction these applications are getting with corporate IT.
